A coalescence model for freely decaying two-dimensional turbulence
– We propose a ballistic coalescence model (punctuated-Hamiltonian approach) mimicking the fusion of vortices in freely decaying two-dimensional turbulence. A temporal scaling behaviour is reached where the vortex density evolves like t. A mean-field analytical argument yielding the approximation ξ = 4/5 is shown to slightly overestimate the decay exponent ξ whereas Molecular Dynamics simulatio...
متن کاملFreely decaying weak turbulence for sea surface gravity waves.
We study the long-time evolution of deep-water ocean surface waves in order to better understand the behavior of the nonlinear interaction processes that need to be accurately predicted in numerical models of wind-generated ocean surface waves. Of particular interest are those nonlinear interactions which are predicted by weak turbulence theory to result in a wave energy spectrum of the form of...
متن کاملEvolution of magnetic fields in freely decaying magnetohydrodynamic turbulence.
We study the evolution of magnetic fields in freely decaying magnetohydrodynamic turbulence. By quasilinearizing the Navier-Stokes equation, we solve analytically the induction equation in the quasinormal approximation. We find that, if the magnetic field is not helical, the magnetic energy and correlation length evolve in time, respectively, as E(B) proportional to t(-2(1+p)/(3+p)) and xi(B) p...
متن کاملTime-Decaying Bandits for Non-stationary Systems
Contents displayed on web portals (e.g., news articles at Yahoo.com) are usually adaptively selected from a dynamic set of candidate items, and the attractiveness of each item decays over time. The goal of those websites is to maximize the engagement of users (usually measured by their clicks) on the selected items. We formulate this kind of applications as a new variant of bandit problems wher...
متن کاملMetal-like Electrical Conductance in Boron Fullerenes
Electron transport properties of B-fullerenes, B80 and B100, are investigated with the use of the first-principles density functional theory (DFT), in conjunction with the Landauer-Büttiker formalism and compared with C-fullerene, C60, under similar conditions. The differential conductance and the tunnel current for B-fullerenes sandwiched between Au contacts are calculated to be much higher th...
